THEATER CHAIR.

Application filed June 14, 1921.

To all whom. t may 00a-cera.'

Be it known that I, LoUrs ROTH, a subject of Austria-Hungary, residing at the city of New York, county of Bro-nx, and .State of New York, have invented a certain new and useful Theater Chair, of which the following is a specification.

This invention is a chair for use in theaters, moving picture houses vand @auditoriums generally, and the object in view is to cont-rol the flow of a warming or cooling atmosphere within the .aisle between adjacent rows of chairs.

In a, prior application file-d by me `on May 20, 1920, Serial No. 382,731, there; is Vdisclosed one embodiment of means for directing the flow of air by way of a grill positioned-at the lower partof a chair.

According to the present invention, the duct for the inflowing' atmosphere vis extended upwardly to the arm of the chair, and a plurality of grills are used, the area of the openings in said ,grills being equal substantially to the cross sectional area of the duct for feeding the atmosphere whereby the flow of air into the laisle is unimpeded.

The invent-ion embodies ,means for yadapting the chair to the slope or level condition of the .floor upon which said chair is 4to be installed, and to this end I employ a base in either of two forms in one of which the bottom portion is horizontal to suit a level floor, whereas in another form the base has an inclined lower portion the inclination of which corresponds substantially to the slope of the floor.

Other functions and advantages ofthe invention will appear from the following description taken in connection with the drawings, wherein- Figure 1 is a side elevation of a chair einbodying the invention.

Figure 2 is a vertical cross section taken in the plane of the dotted line 2-2 of Figure 1.

Figure 3 is a horizontal cross section in the plane of the dotted line 3 3 of Figure 1.

Figure l is a detail view in side elevation off a form of the base adapted for a sloping floor.

A designates a chair frame which is usually of cast metal and of desired form, ornsamental or otherwise. Said frame is skeletonized for the reception of an air distributing grill, the latter being composed, in the Serial No. 477,397.

example shown, of two parts, an upper grill part B and a. lower grill part C. Each ,grill part isr cast or otherwise formed in a single piece of metal, the same being provided with openings b for the free flow of air through the grill. The parts B C composing the grill are shaped and proper'- tioned to lit wit-hin the skeletonized frame A,

lto which frame said grill parts are secured lixedly by appropriate means. The grill parts are, or inlay, be of an ornamental charlacter, and the two parts are separately attached to the `chair frame so that theI meeting edges of said grill parts may have a desired relation, it being preferred to provide .the upper grill part B with'a hood c at the lower edge thereof, said `hood extending crosswise ofv grill B and sa-id hood pro- .the floor of the auditorium, but it is pre.-

ferred to employa hase G to which the lower part of the chair frame is suitably attached. The base G is shown in Figures 1 and 2 as adapted .to be secured to a horizontal floor, all parts ofthe base being equal in height, but it happens quite frequently that chairs are to be secured to slopingor inclined floors. in which event I employ a tapering base G. the lower floor line g of which. is inclined to correspond with the slope of the floor. see. Figure t. The tapering base rests firmly upon the sloping lioor and it aords a horizontal, or substantially horizontal, upper surface upon which rests the chair frame so as to occupy/the required vertical position, it being understood that the base is fiXedly attached to the floor' and the chair frame is in like manner attached tothe base. i

H is a flue plate positioned within the limits of the chair frame and 'in facing relation to the grill parts therein so as to form a ue I. The flue plate is of channelled form in cross section, see Figure 3, the lower part of said plate being expanded or `enlarged vat 71J in order to register with the feeding flue I provided in thefloor `of the auditorium. see Figure 2. S'aid flue plate lies within the limits of the chair frame, eX-

tending upwardly to the arm rest D so as to have a compact relation to the chair frame and to the seat, see Figure 2, whereas the expanded lower part lz. of the Hue plate is in register to Hue I, to permit the free How of air into the distributing space, chamber or Hue formed by and between the Hue plate and the grill parts B C. The use of a grill in two parts and of a Hue plate extending substantially to the arm rest of the chair provides for the upward extension of the distributing space within the limits of the chair frame, and provision is thus made in the grill parts B C for openings the aggregate area of which is equal substantially to the cross sectional area of the Hue space or of the Hue I, whereby the metal grill B C affords no obstruction to the out- How of the current of air; but, on the contrary, the air is free to How without impedance by the presence of the grill, the hood c of grill part B having a tendency to direct the inHowing air downwardly toward the Hoor of the aisle.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is:

l. In a chair of the class described, the combination with a chair frame, of an imperforate Hue pla te extending from the Hoor line upwardly with respect to the chair frame and materially above the seat portion thereof, said Hue plate having a lower portion inclined to the plane of the chair frame and an upper portion in substantially parallel relation to said chair frame, and al plurality of grills in fixed relation to the chair frame and in opposing relation to the iniperforate Hue plate, the area of the opening in the grill being equal substantially to the cross sectional area of a Hue provided by and between the grill and the Hue plate.

2. In a chair of the class described, the combination with a chair frame, of an imperforate Hue plate extending from the Hoor line upwardly with respect to the chair frame and materially above the seat portion thereof, said Hue plate having a lower portion inclined to the plane of the chair frame and an upper portion in substantiall parallel relation to said chair frame, an a plurality of grills positioned in substantially vertical alinement with each other and within the chair frame, one of said grills being opposite to and parallel with the upper portion of said imperforate Hue plate and the other of said grills being opposite to the lower inclined part of said'imperforate Hue plate.

3. In a chair of the class described, the combination with a chair frame provided with an arm rest, of an imperforate Hue plate extending upwardly within the chair frame substantially to the level of the arm rest, and a divided open-work grill positioned in facing relation to said Hue plate, the upper part of the grill being provided at its lower portion with a hood which protrudes beyond the vertical plane of the grill.

4. In a chair of the class described, the combination of a hollow Hoor base the bottorn edge of which is inclined according to the slope of the Hoor, a chair frame erected upon the Hoor base, a Hue plate in communication with said hollow base extending upwardly from the Hoor line and within the limits of the chair frame, said Hoor base being separate from' the chair frame and the Hue plate, and an open-work grill secured to the chair frame in facing relation to the Hue plate.

5. A chair framesleletonized for the reception of an air-distributing grill, and a grill composed of an upper part and a lower part, said grill parts being formed separately and having openings for the How of air, the one part resting upon the other and the two parts Htted within said frame, and separately attached thereto, and a Hue plate positioned within the limits of said frame and in facing relation to said grill parts, said Hue plate being of channeled form in cross section with the lower part inclined and expanded opposite the lower grill part,

said Hue plate extended upwardly and ma- .f

terially above the seat portion of the chair, thearea of the openings in the grill parts being equal substantially to the cross sectional area of the AHue space between the grills and the Hue plate.

6. A chair frame skeletonized for the reception of an air-distributing grill, and a grill composed of an upper part and a lower part, said grill parts being formed separately and having openings for the How of air, the one part resting upon the other and the two parts Htted within the said frame, and separately attached thereto, and a Hue plate positioned within the limits of the said frame and of channeled form in cross section with the lower part inclined and expanded opposite the lower grill part, said Hue plate being extended upwardly and materially above the seat portion of the chair, the area of the openings in the grill parts being equal substantially to the cross sectional area of the Hue space between the grills and the Hue plate, the upper grill part being provided at its lower edge with a hood at a point opposite the upper` part of the inclined wall of the Hue plate'y and extended beyond the plane of the top of the lower grill part.

In testimony whereof I have hereto signed my nam-e this 7th dayV of J une, 1921. l
